$HOE CONSTRUCTION.

Specification of Letters Patent.

Patented Aug. 3t, 1915.

Application filed April 13, 1915. Serial No. 21,044.

To all whom it may concern:

Be it known that I, JOHN DEMIeN a subject of the King oi Hungary, residing at Cleveland, in the county of (Juyahoga and State of Ohio, have invented certain new and useful improvements in Shoe Construction, of which the following is a specification.

This invention relates to new and useful improvements in shoe construction.

The primary object of the invention is the provision of a shoe'adapted for use by especially adapted for walking over rough workmen employed in metal mills, such as steel rolling mills, and whereby the workman is slightly elevated 0d of the floor while walking and is also able to walk over the hot plates without injuring his feet.

- A further object is the provision of a shoe for workmen having metallic bearing surfaces and -.a resilient heel member and being as well as heated surfaces.

A still further object is to provide a thick soled shoe having a resilient heel and provided with removable tread plates, the entire sole of the shoe being adapted to elevate the-wearer above the ground.

With these general objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the appended claims.

In the drawings forming a part of this application and in which like designating characters refer to corresponding parts throughout the several views:-Figure l is a side elevation of a shoe provided with. the present device and having the sole and adjacent portion thereof illustrated in central longitudinal section. Fig. 2 is a top plan view of the sole removed from the shoe. Fig. 3 is a bottom plan view of the heelportion of the sole. Fig. 4 is a perspective view of one of the resilient gaskets employed with the spring heel of the device.

Referring more in detail to the drawings, the shoe upper 10 is illustrated as having the present form of. sole member secured thereto, the said sole having a main foundation member 11 securedto the upper in substantially the usual manner as at 12 and being provided with an extra thick form of insole 13 flatly engaging the inner surface thereof. The f undation sole 1.1 may be formed of leather, wood or other appropriate material, and has a ball or tread portion 14 and a heel portion 15.

A block 16 of the same dimensions as the front portion 14 is secured to the latter by means of bolts which extend through perforations of the front member 14 and also through perforations of the block 16, the heads 20 of the bolts lying beneath the insole 13 and provided with bearing washers 21 encircling the said bolts as shown in Fig. 2. A bearing or trade plate 24 is flatly secured to the lower face of the sole block 16 by means of a centrally positioned screw 25 which is projected therethrough and is screwed into the said block 16. This tread plate is preferably formed of metal to allow walking over heated surfaces and plates while the block 16 and the sole foundation 11 are formed of heat insulating material, and thus unitedly prevent the heating and injury of the feet of the wearer.

A heel block 27 is mounted upon the heel portion 15 of the foundation sole 11 while an outer layer 28 flatly engages the same,- the said layer 28 and block 27 being secured to the heel 15 by means of screws as best illustrated in Figs. 1 and 2, the heads 30 of the said screws being positioned beneath the insole 13. A tread plate 31 for the heel is secured by means of screws 32 to the lower face of the heel layer 28.

A central chamber is provided in the heel by the provision of central perforations 33 extending through the heel l5, block 27 and layer 28. A coil spring 34 is mounted within the heel chamber and is provided at its opposite ends with resilient cushions 35 preferably formed of rubber or other suitable resilient material, and being of the form best illustrated in Fig. i. The said heel spring is thus mounted by means of the said cushions 35 between the plate 31 and the insole 13, the weight of the spring there by resting upon the plate 31;. It will be noted that the tread portion of the sole and heel being spaced a considerable distance from the insole 13 which is of increased thickness practically renders the insole heat insulated.

Fromthis detailed description of the present device, it will be seen that the comso1e13; The inner sole 13 resting with its heel portion upon the'upper cushion 35 of the resilient spring 34:, imparts a slight resiliency to the device and whereby the wearer willbe given substantially the same effect as though the entire shoe sole was formed of the usual flexible material. A shoe is thus provided that is serviceable for workmen in walking upon heated surfaces but at'the same time is comfortable to the wearer. I

7 What I claim as new is 1. A shoe provided with a sole member, a metallic tread plate, a heat insulating block secured between the tread plate and sole member, the heel of said sole being provided with a central chamber therein, a coil spring within the said chamber, terminal cushions carried by the said spring and seated upon the metal plate of the said heel, and an inner sole'within the shoe and having the heel portion thereof mounted upon the inner end of the upper cushions.

2. A shoe including a heel comprising a pair of lower lifts having central openlngs therein a metal plate covering the lower lift,

copies of this patent may be obtained for five cents each, by addressing the the opening in the upper lift being smaller than the opening in the lower lift, a coil an opening therein with a contracted central portion, a bottom plate forming a closure for said heel, an insole spanning the opening at the upper end of, the heel, a coil spring mounted in said opening and guided by the contracted central portion, and cushion blocks having opposed bosses received in the ends of the spring, one block resting on the bottom plate and the other block engaging the insole. I In testimony whereof I affix my signature in presence of two Witnesses.
